Overview

Opera Presto rendering engine

This document and its associated support tables apply specifically to the Opera Presto 2.7 rendering engine. It incorporates Opera Presto web specification support up to, and including the latest Core Milestone and integration point. Changes and additions occurring since Opera Presto 2.6 are identified with their specific Core Milestones. Please see the following Core Milestone integration points added since Opera Presto 2.6 topic.

Opera desktop, device, and mobile products

Opera products use and depend upon various parts of the Opera Presto rendering engine and its web specification features. It is important to note that while the latest Opera Presto rendering engine has incorporated new web specification features, they may not have been added to the latest released versions of Opera products.

The Opera user agent string

Opera products will identify which Opera Presto version and Core Milestone integration point they are using in their user agent string. Depending on your Opera product, the Opera user agent string is placed in the "About Opera" page, found by typing opera:about in the address bar, or by clicking "Help > About Opera" in the Menu. Here is an example:

Opera/9.80 (Windows NT 5.1; U; en) Presto/2.7.62 Version/11.01

This example user agent string belongs to Opera 11.01 for desktop. It describes that it is using the Opera Presto 2.7 (Presto/2.7) rendering engine, incorporating Core Milestone integration point 62 (.62). This Opera desktop product can contain web specification support as provided in Opera Presto 2.7, Milestone 65 core integration point 62 and earlier. It does not contain web specifications which have been included in later builds of Opera Presto 2.7 with Core Milestone 65 core integration point 63 and later.

A high-level overview of current web specifications support in Opera products is available on opera.com at: Web specifications support in Opera products: an overview.
